Hi Mike. MySQL version is 5.7.13. I've another question: what happens when I face this error? Before changing these settings, can I try to upload the XML as a new style and check what happens? If I face the error, it will simply abort the process or it can mess up things?

my MySQL version on production server is libmysql - 5.1.73. Data taken from phpmyadmin. Does this change something?

Not really. The issue here is specific to the server version. Though be aware that running a PHP mysqli extension and a MySQL server with very different versions can potentially cause issues. (Unless you're running into odd behaviors or other errors, it's unlikely to be a problem right now though.)

Not sure what do you mean with this. Do you mean that with version lower than 5.6.22 I will not face the error "Row size too large (> 8126)"? So considering my mySQL version I don't have to fix the "innodb_log_file_size = 5M"?

You specifically mentioned libmysql, so I assume you pulled that from your PHP info. That's explicitly not your MySQL server version; it's referencing a library that PHP has been compiled against. You need to connect to your MySQL server to get the exact version.

From phpmyadmin:
So I think this confirms that MySQL version is 5.1.73, right?

So again with the question: considering that I'm on a MySQL version lower than 5.6.22, I will not face the error "Row size too large (> 8126)" or there're the same probabilities to face it anyway?
